Try this

function toASCII(chars) {

    var ascii = '';

    for(var i=0, l=chars.length; i<l; i++) {

        var c = chars[i].charCodeAt(0);



        // make sure we only convert half-full width char

        if (c >= 0xFF00 && c <= 0xFFEF) {

           c = 0xFF & (c + 0x20);

        }



        ascii += String.fromCharCode(c);

    }



    return ascii;

}



// example

toASCII(ＡＢＣ); // returns 'ABC' 0x41
